The deep frying process isn't just useful for livening up your food -- it might also be the ticket to better batteries in your mobile devices. South Korean researchers have created highly conductive, stable electrode materials by spraying graphene oxide droplets into a very hot blend of acid and organic solvent, much like you'd dip chicken into oil. The resulting "pom-poms" (what you see above) aren't at all tasty, but their open 3D structure makes them far better for transferring electrical charges than plain graphene.

Climate change is still real, still happening and still terrifying, but thankfully it looks as if the US and China are listening to the UN's advice. The pair has announced a historic pact that sees both nations agreeing to begin reducing their carbon emissions by 2030 at the very latest. The US is going further, pledging to reduce its emissions by up to 28 percent of 2005 levels - which would bring annual emissions down from six billion tonnes per year to just over four. China, on the other hand, is promising to "peak" its emissions by 2030 or earlier, meaning that the number will start to fall after that point. The downside of that, of course, is that China could be pumping up to 12 billion tonnes of CO2 before it starts to make a dent.

The lithium ion batteries in your mobile devices are inherently limited by the "ion" part of their name; they can safely use lithium only in the part of the cell that supplies ions, wasting a lot of potential energy. It's good news, then, that researchers at Stanford have developed a new lithium battery that could last for much, much longer. The technique allows for denser, more efficient lithium in the battery's anode (which discharges electrons) by using a nanoscopic carbon shield that keeps the unstable chemical in check -- uncontrolled, it can quickly shorten the device's lifespan.

It could be centuries (if ever) before humans can observe the behavior of a supernova first-hand, but scientists at the University of Oxford may have delivered the next best thing. They've recently simulated an exploding star by zapping an extremely thin carbon rod with a powerful laser; the resulting extra-hot blast (1.8 million degrees Fahrenheit) ripped through a chamber much like the real thing, as you can see pictured here. To add an extra dose of realism, the team added a plastic grid that replicated interference from dust and gases.

In an effort to reward programme makers for doing their bit for the planet, the BBC will soon start displaying a seal of approval on shows that are greener than most. In partnership with BAFTA, the Beeb will award TV programmes that "meet higher environmental standards" with a new "Albert+" certification badge on the credits. To be eligible for the badge, content producers need to have a strong focus on sustainability, share those goals with cast and crew, measure their carbon footprint and take the necessary steps to reduce carbon emissions when filming. Quite the list, but two programmes (From There To Here and Springwatch) have already earned their green (or should it be gold?) stripes and are set to air in the next week. Despite its small beginnings, the BBC and BAFTA hope that other UK producers and broadcasters will follow suit, making Albert+ "the expected standard for all publications."

One of the biggest arguments against fixing climate change is that it would cost too much. Not so, says the UN's climate change panel, which has found that abandoning fossil fuels would only knock around 0.06 percent off the world's GDP. According to the report, if low-carbon energy quadruples by 2050, then the planet may only warm by two degrees -- the upper limit before The Day After Tomorrow-style catastrophes are commonplace. The panel recommends switching to renewables like solar, wind and hydropower, with nuclear the next best option and biofuels in third, since the latter uses the same land and resources needed for growing crops. Maybe it's time that we all started cycling to work.

In many ways, plants are ideal technology hosts -- they're outdoor-friendly, self-healing and pollution-free. It only makes sense, then, that MIT scientists want to harness that potential by augmenting our leafy friends with nanotechnology. The researchers have found that injecting nanoparticles and carbon nanotubes into a plant can extend its natural abilities, or add functions that would be tricky to replicate with purely synthetic devices. One lab test supercharged photosynthesis, extracting much more energy than normal; another introduced gas sensors that could detect the nitric oxide from a car's exhaust. There's a lot of necessary refinement before bionic plants are practical, but we won't be surprised if our gardens eventually double as energy sources and air quality monitors.

It's tough to build solar cells that capture both heat and light -- most of these multi-talented devices can't trap more than one percent of the energy they receive. However, MIT has just blown past that limitation with a prototype chip that absorbs warmth through an outer layer of carbon nanotubes. The tubing heats up photonic crystals so much that they glow with an intense light, giving an attached solar cell more energy than it would collect through sunlight alone. The technology is already efficient enough to extract 3.2 percent of the energy it gets, and MIT believes that it could reach 20 percent with more development. While that's not necessarily more effective than conventional technology, it's much easier to store heat than electricity; a future nanotube-based panel could provide a lot more on-demand energy than we typically get today. There's no estimate for when a finished product might reach the market, but it might not be long before solar panels have plenty of reserve power.

Lenovo's ThinkPad X1 Carbon is such a beautiful piece of hardware that we're having trouble concentrating. With that carbon fiber chassis, the Ultrabook is thin, light and classily understated. Even packing Ivy Bridge internals, it still managed to crank out five hours of battery life and, aside from its slightly weak display, stands head and shoulders above other skinny carbon laptops we could mention. But what about you high-rollers who splashed out upwards of $1,400 on one of these things? Here's the time for you to share your experiences and tell us what you would change.

Harnessing the awesome power of the Sun isn't just dependent on the efficiency of solar cells, but also on making them affordable. Current techniques aren't exactly cheap, but researchers from StanfordUniversity think they've made a bit of a breakthrough by producing a relatively inexpensive photovoltaic cell using nothing but carbon. We're sure other scientists might disagree with the 'world's first' claim, but those at Stanford think it's a matter of language, and that these other pretenders are "referring to just the active layer in the middle, not the electrodes." The team selected a trio of carbon types to use in their cell: a mixture of nanotubes and buckyballs make up the light-absorbing layer, while graphene is being utilized for the electrodes.

The carbon amalgam can be applied from solution using simple methods, meaning the flexible cells could be used to coat surfaces, although you won't be seeing it smeared over anything too soon. The prototype only touts a "laboratory efficiency of less than 1 percent," so it can't compete with traditional solar cells just yet. Also, it only absorbs a sliver of the light spectrum, but the researchers are looking to other forms of the wonder element which could increase that range. They are hoping that improving the structure of the cells will help to boost their efficiency, too. They might never generate the most energy, but the all-carbon cells can remain stable under extreme conditions, meaning they could find their calling in harsh environments where brawn is a little more important than status, or looks.

Commercialization of carbon nanotubes is one of the holy grails of next-gen computing, and IBM thinks it's made crucial steps toward making this a reality. This isn't the first time that we've heard such a claim, of course, but IBM's considerable resources will make this particularly interesting. The specific problem it's been tackling is placing enough semiconducting nanotubes together to be useful in commercial chips, with current attempts being more in the hundreds, rather than billions that would be required. The new approach uses ion-exchange chemistry that allows controlled placement of nanotubes at two orders of magnitude greater than before, with a density of roughly a billion per square centimeter. To achieve this, the nanotubes are mixed with a soap-like substance that makes them water-soluble. Next, a substrate comprising two oxides and a hafnium oxide "trench" is immersed in the soap-solution, which results in the nanotubes attaching to the hafnium oxide canals with a chemical bond. Simple when you think about it! IBM hopes that as the materials and method are readily accessible now, that industry players will be able to experiment with nanotube technology at a much greater scale. Though, as we've become accustomed, there's no solid timescales on when this might realistically unfold.

Want to know how the BMW i3 electric car can be so light (2,800 pounds) despite hauling around a massively heavy battery pack? A lot of it has to do with its carbon chassis. BMW uses something called CFRP (carbon fiber reinforced plastic) to create a material that is light, strong and, crucially, cheap enough to actually be used in production. The car is still on track for its 2013 release, where it will be sold out of posh i Stores like the one recently opened in London.

Japanese company Green House Co Ltd has quite an eclectic product portfolio, what with its women-only camcorder and peripherals like a PCI Express interface card with USB 3.0 support. Its latest device falls under another category entirely: the rivetingly named GH-LED10WBW is an LED lantern that runs on just water and salt; no batteries required. The light source provides eight hours of electricity per dose of saline water, and the lantern comes with a dedicated water bag for mixing the solution. The salt / water combo acts as an electrolyte with the magnesium (negative electrode) and carbon (positive electrode) rods inside the lantern. Users can get about 120 hours of power with the Mg rod before they'll need to buy a replacement (the rod is sold separately to begin with). More than just supplying a battery-free source of light, though, the lantern can function as a charger, thanks to a USB port built into the casing. Pricing has yet to be announced, but the GH-LED10WBW will be available by mid-September.

Remember when we told you last week that we live in a strange world? Well, we had no idea what we were talking about. Seriously, things are about to get a whole lot weirder. High school is certainly a head-scratcher, no matter how old you are, but the mathematics of social hierarchies can't hold a candle to the mysteries of the buckyball. And, if the strange behavior of the familiar carbon molecule isn't enough for you, we've got an entirely new molecule to contend with, while the once-elusive Higgs Boson is getting us closer to unlocking the secrets of the universe. It's all pretty heady stuff, which is why we're also gonna take a quick detour to the world of human waste. This is alt-week.

Greenery may fulfill a superficial need to improve the landscape aesthetic, but plants play a much more critical role in regular life function, converting carbon dioxide to oxygen through a process called photosynthesis. Panasonic is among the companies attempting to replicate this natural procedure through artificial means, and it looks like the Japanese electronics maker is well on its way towards a viable solution. Presenting at the International Conference on the Conversion and Storage of Solar Energy this week, Panasonic announced the development of an Artificial Photosynthesis System, which uses a nitride semiconductor to convert water and carbon dioxide -- a byproduct of factories and power plants -- into an organic material called formic acid, which is used in the manufacturing of dyes and fragrances. Covering the planet in formic acid wouldn't necessarily represent progress, but assuming demand isn't exceeded, it certainly beats CO2. Best yet, Panasonic claims that the system converts the substances at plant-like efficiency rates, or 0.2 percent. Hit up the PR after the break for a more granular look at the company's creation.

Archos' recently outed 97 Carbon is the poor man's Android slate... intentionally. Part of the French outfit's low-cost Elements line, the 9.7-inch ICS tablet saw an official unveiling earlier this month and is now making an obligatory step-and-repeat at the FCC. We've already been given the full rundown on the tab's innards -- single-core 1GHz CPU, ports for HDMI-out, micro-USB, USB, dual camera setup and vacant microSD slot to complement the 16GB of storage onboard -- so there's not much new info to glean from the filings, aside from some candid lab shots. Regardless, feel free to hit up the source below to tour it all, or just navigate your way to an online retailer if you'd rather own this one IRL.

Slowly, but surely graphene is pushing our technological hopes, dreams and, yes, nightmares towards reality. The stuff is capable of extending battery life, generating electricity, powering high-speed data connections and super computer-worthy CPUs. It's water proof, stretchy, bendy and apparently self healing. (This space reserved for T-1000 reference.) Researchers at the University of Manchester discovered that, if you put a hole in a sheet of graphene, it simply stitches itself back together. This is thanks to carbon's tendency to latch on to other atoms, including its own, which can make the futuristic material difficult to work with, but gives it this highly unique quality. Thankfully, we're no where near self-healing robots. But, the discovery could lead to a simple method for molding it into almost any shape. Once pierced, the form of the mend is determined by the type of molecules introduced -- pure carbon simply regrows the perfect honeycomb structure, while a few foreign atoms can lead to "defects." Of course, if they're intentional and predictable, defects merely become "features." For more check out the source link.

Those worried that Archos hasn't introduced a line of low-cost Android tablets in a while have reason to breathe a collective sigh of relief. The company's gearing up for the launch of its "Elements" series, beginning with this month's release of the 97 Carbon. No chipmunks this time out, sadly, but the Ice Cream Sandwich slate does sport a 9.7-inch IPS display, a 1GHz processor, HDMI out and a full-sized USB port. Also on-board are two cameras, 16GB of storage and a microSD slot, packed into a 0.45-inch thick aluminum body. The 97 Carbon runs $230 to $250. Archos is promising more entries in the "entry-level" Elements lineup, measuring seven, eight and 9.7 inches. Press info on this particular model can be found after the break.

Astronomers in Chile using the European Southern Observatory's Very Large Telescope are now able to analyze the atmosphere on faraway planet Tau Bootis b. Using CRIRES, a supercooled infrared spectrograph bolted to the 'scope, the team was able to judge the size of the exoplanet -- and for the first time, take a reading of the atmosphere while not in transit. Historically, the only time researchers have been able to conduct atmospheric analysis is during the transit of its nearby star, which imprints the qualities of the atmosphere onto the light. The team found that Tau Bootis b is around six times the size of Jupiter, but its air is so thick with Carbon Monoxide that we'll have to look elsewhere to plan that expedition to the stars.

What's this orange-like patch, you ask? It's a layer of carbon nanotubes on silicon, and it might just be instrumental to getting a lot more power out of solar cells than we're used to. Current solar power largely ignores near-infrared light and wastes about 40 percent of the potential energy it could harness. A mix of carbon nanotubes and buckyballs developed by MIT, however, can catch that near-infrared light without degrading like earlier composites. The all-carbon formula doesn't need to be thickly spread to do its work, and it simply lets visible light through -- it could layer on top of a traditional solar cell to catch many more of the sun's rays. Most of the challenge, as we often see for solar cells, is just a matter of improving the energy conversion rate. Provided the researchers can keep refining the project, we could be looking at a big leap in solar power efficiency with very little extra footprint, something we'd very much like to see on the roof of a hybrid sedan.

Gigabyte is clearly hoping to carve out a name for itself in a very crowded ultraportable space; it sent us word of a media event for a new X11 laptop in its native Taipei on May 31st, just a few days ahead of Computex. The PC designer claims that the X11 will be the "lightest notebook on Earth," a pretty audacious claim considering the featherweight competition. Most of the braggadocio, we suspect, is rooted in the choice of material: Gigabyte is promising rather ominously to "conquer the 6th element," and unless it's financing the sequel to a Luc Besson movie, we're reasonably sure the firm means extra-light carbon fiber. Other details are scarce, including whether there's any relation to the U2442 Ultrabook due this summer. We'll know in just over a week.

Yes, that laptop you see up there is called the ThinkPad X1 and yes, it's the successor to the X1 we reviewed around this time last year. But, folks, this isn't your typical refresh. The X1, once a 13-inch system, has grown up into a 14-inch ultraportable, now being marketed as an Ultrabook. Despite gaining an inch in screen real estate, though, it manages to be both thinner and lighter than its predecessor: 3.0 pounds and roughly 18mm (.71 inches) thick, down from 3.7 pounds / .84 inches. (As the name suggests, carbon fiber is the secret ingredient.) Chances are, you won't have the luxury of comparing the two systems side by side, but coming from someone who reviewed the original, we can assure you the difference is noticeable, even going off of sheer muscle memory. That bodes well for people picking up the X1 for the first time.

But those aren't the only changes the X1 has undergone. Lenovo also bumped the resolution from 1366 x 768 to 1600 x 900, and made some subtle tweaks to the backlit, spill-resistant keyboard. 3G connectivity is also a major selling point, though that was an optional feature last time around, too. As you could've guessed, it packs an Ivy Bridge processor, coupled with Intel's vPro management technology and (we assume) integrated graphics. Like the last-gen model, it makes use of Lenovo's RapidCharge tech, which allows the notebook to re-charge up to 80 percent capacity in 30 minutes. Unfortunately, though, the company's staying mum on battery life claims for the time being. Another teensy detail we don't know? Price. So far, we only know it'll go on sale sometime this summer. Until then, though, check out some teaser shots below, along with a short hands-on video after the break.

We've seen quite a few tech companies boast about their environmental efforts in recent years, and it looks like you can now also add Microsoft to the list of those attempting to be carbon neutral. As you might expect, while that includes some alternative energy efforts and energy-saving measures, it also makes use of a carbon offset program to make up the difference, which will see Microsoft put money into an internal fund for emissions it's not able to offset through other means. That means Microsoft will be able to declare itself carbon neutral fairly soon -- by the start of the 2013 fiscal year, to be specific, which actually begins this July. You can find additional details on the initiative in the company's blog post on the subject, and yet more in the white paper linked below.

Good, because the latest news published in Nature is that diamonds are a quantum computer's best friend -- particularly if they're flawed. An international team of scientists sought out sub-atomic impurities in a 1mm-thick fragment of over-priced carbon and used these as qubits to perform successful calculations. A "rogue" nitrogen nucleus provided one qubit, while a free electron became a second. Unlike previous attempts at solid-state quantum computing, this new effort used an extra technique to protect the system from decoherence errors: microwave pulses were fired at the electron qubit to "time-reverse" inconsistencies in its spinning motion. Don't fully get it? Us neither. In any case, it probably won't stop jewellers tut-tutting to themselves.

It's nine nanometers in size, making it one nanometer smaller than the presumed physical limit of silicon transistors. Plus, it consumes less power and is able to carry more current than present-day technology. The researchers accomplished the trick by laying a nanotube on a thin layer of insulation, and using a two-step process -- involving some sort of black magic, no doubt -- to add the electrical gates inside. The catch? (There's always a catch) Manufacturing pure batches of semiconducting nanotubes is difficult, as is aligning them in such a way that the transistors can function. So, it'll be some time before the technology can compete with Intel's 3D silicon, but at least we're one step closer to carbon-based computing.
